WILLIAM NELSON MARTIN, OF BOSTON, MASSACHUSETTS.

IMPROVEMENT-IN BINDERS FOR SEWING-MACHINES.

Specification forming part of Letters Patent No. 125,590, dated April 9,1872.

To all whom it may concern.

Be it known that 1, WM. NELSON MARTIN, of Boston, in the county ofSuffolk and State of Massachusetts, have invented anew and usefulImprovement in Attachments for Sewing.

Fig. I I is a sectional view through the line was.

Figs. III, IV, and V are views of the spring K and curved plate 6. Fig.VI is a view of the braid or galloon-carrier.

My invention has for its object to provide an improved adjustable binderattachment for sewing-machines, adjustable to the dilferent machines nowin use, and as an improvement on my patent dated May 15, 1870, reissuedMay 9, 1871. It consists in a circular slotted plate, which revolves,and allows a ready adjustment at any point within the circle formed bythe slot as its radius. It also consists in anovel-shaped spring forholding the curved plate 0 in position; also in a novel arrangement ofthe braid or galicon-holder.

To enable others skilled in the art to understand and use my invention,I will proceed to describe the manner in which I have carried it out.

A is a bed-plate, having a circular opening and shoulder, t'. Withinthis circular opening 1 tit a circular plate, B. having in it a slot,-0, and shoulder, i, and which rotates freely within the opening in theplate A, the shoulder z" fitting on the shoulder 2'. Through theslot 0passes the thumb-screw holding the binder to the machine, by which it isevident the binder may be adjusted to any machine whose thumbscrew holecomes within the circle traversed by the slot 0. When the plate B isadjusted within the plateA as desired, it may be held in position whennot in use by the screw N andbraid-holder M. K is a spring attached tothe curved plate 6, and bearing upon the opposite sides of the standardL of the guide-plate. This spring holds the curved plate ein properposition, and it moves up and down with the arm D, and is adjusted withthe arm 0 by means of the adjusting-screw G. M is a braid orgalloon-carrier, attached to 'the bed-plate A by the screw N, and is ofthe peculiar shape shown in Fig. VI.

I am aware that sewing-machine attachments have been rendered adjustable-by means of slots moving in straight lines, as is shown in thepatent of E. Bostock, dated July 28, 1868. I therefore do not claim,broadly, an adjustable plate for sewing machine attachments; but-- WhatI claim, and desire to secure by Let ters Patent, is-

1. I claim the spring K, constructed as described, in combination withthe curved plate 0, substantially as and for the purpose set forth.

2. In combination with a binding attachment having the spring and curvedplate, as specified, I claim the revolving slotted plate B and bed-plateA, substantially as and for the purpose set forth.
